📥 The "import.php" file used in this tutorial is also provided with the video so you can use the same method on your own cPanel hosting account.
🚀 What You’ll Learn
✅ Upload a large ".sql" database directly to cPanel
✅ Create and configure a MySQL database
✅ Configure database host, username, password and database name
✅ Use "import.php" to process the SQL file
✅ Import a large database without uploading the entire file through phpMyAdmin
✅ Monitor the import progress
✅ Verify the imported database after completion
🛠️ How It Works
Normally, you can import a database through:
cPanel → phpMyAdmin → Import → Choose SQL File
However, large SQL files can encounter limitations such as:
• Maximum upload size
• PHP "upload_max_filesize"
• "post_max_size"
• "memory_limit"
• "max_execution_time"
• Web-server timeout
• phpMyAdmin limitations
With this method, the SQL file is first uploaded directly to the hosting server. The PHP importer then reads the SQL file from the server and executes the SQL statements through MySQL.
📌 Step-by-Step
1. Create the Database
Go to:
cPanel → MySQL® Databases
Create your database and database user, then assign the required privileges.
2. Upload the SQL File
Open:
cPanel → File Manager
Upload your large ".sql" backup file.
The supplied "import.php" expects the SQL file to be in the same directory and uses the configured SQL filename.
For example:
"public_html/import.php"
"public_html/91club.sql"
3. Configure import.php
Open "import.php" and enter your own:
• Database Host
• Database Username
• Database Password
• Database Name
• SQL File Name/Path
The script connects to MySQL using these credentials before starting the import.
4. Run the Importer
Open the PHP file through your browser:
"https://yourdomain.com/import.php"
The script checks for the SQL file, connects to MySQL and begins processing the database.
A live progress bar is displayed while the import is running.
The importer counts the SQL file lines and then processes the file line by line, building and executing queries when a statement ends with a semicolon.
The progress percentage is updated while the import continues.
Once processing finishes, the script displays Import Completed!
📥 IMPORT.PHP FILE
The "import.php" file demonstrated in this video is provided with the tutorial.
Before using it, configure it with your own database credentials and SQL filename.
The script includes PHP settings intended to allow longer execution and higher memory usage and controls output buffering so progress can be displayed during the import.
⚠️ IMPORTANT SECURITY WARNING
Never use or publicly share an importer containing real database credentials.
Replace the credentials in the example file with your own before using it.
After the import is successfully completed:
🔐 Delete "import.php" from your website.
🔐 Delete or move the ".sql" backup to a secure location.
🔐 Never leave database credentials inside a publicly accessible PHP file.
🔐 Do not expose your SQL backup through a public URL.
⚠️ COMPATIBILITY
This importer processes the SQL file line by line and executes statements when they end with ";". It skips blank lines and certain comment lines.
Because SQL dump formats can vary, not every SQL backup is guaranteed to work with this particular importer. Complex procedures, triggers, custom delimiters or unusual SQL structures may require another migration method.
